3.6 LIN"A" (JP: 17, 18, 21, 22, 44)
One LIN-transceiver (U5, X8) can be connected to one of the microcontroller's UART
interfaces.
JP17
enable LIN-Transceiver
JP18
LIN Master-mode
JP21, JP22 connects UART 0 to the LIN-transceiver (U5, X8)
If the LIN interface is not used then the jumpers should be left open.
Jumper
JP17 (LIN enable)
JP18 (LIN Master)
JP21 (LIN"A"RXD)
JP22 (LIN"A"TXD)
JP44 (VBAT_A)
By default, the LIN"A"-interface is not connected to a UART.
3.7 LIN"B" (JP: 9, 10, 38, 39, 45)
One LIN-transceiver (U4, X6) can be connected to one of the microcontroller's UART
interfaces.
JP9
enable LIN-Transceiver
JP10
LIN Master-mode
JP38, JP39 connects UART 1 to the LIN-transceiver (U4, X6)
If the LIN interface is not used then the jumpers should be left open.
Jumper
JP9 (LIN enable)
JP10 (LIN Master)
JP38 (LIN"B"RXD)
JP39 (LIN"B"TXD)
JP45
(VBAT_B)
By default, the LIN"B"-interface is not connected to a UART.
